VEGFA and coronary artery disorder: These findings could explain the observations of the present study that significant higher mean serum levels of VEGF were detected in C-CHD patients with higher hemoglobin level >10 g./dl than those with lower hemoglobin <10 g./dl and in C-CHD and A-CHD patients with lower SpO2 level <90% than those with higher SpO2 level >90% (Table 4) and the significant positive correlation between the levels of VEGF and hemoglobin and significant negative correlation between VEGF and SpO2 (Table 7).
